WILLIAM O. DUNLAP, OF GEORGES GREEK, TEXAS.

LEMON-SQUEEZER.

SPECIFICATION forming part of Letters Patent No. 434,327, dated August 12, 1890.

Application filed January 18, 1890- Serial No. 337,376. (No model.)

To all whom it may concern.-

Be it known that I, VILLIAM O. DUNLAP, a citizen of the" United States, residing at Georges Creek, in the county of Somervell and State of Texas, have invented a new and useful Lemon-Squeezer, of which the following is a specification.

This invention has relation to improvelnents in lemon-squeezers, and among the obj ects in view are to provide a machine adapted to cut or halve a lemon and extract the juice therefrom and cast away the rinds at one and the same operation.

A further object of the invention is to direct the juice of each half through separate channels, whereby two glasses may at the same time receive their proportionate allowance of lemon-juice to be subsequently converted into lemonade. Although I have herein mentioned the device as particularly adapted to the cutting and squeezing of lemons, yet it will be apparent that the same maybe used to advantage forsimilar operations upon other fruit.

With these general objects in view the invention consists in certain features of construction hereinafter specified, and particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a perspective of a lemon-squeezer constructed in accordance with my invention. Fig. 2 is a longitudinal vertical section of the front portion of the same; Fig. 3, a transverse section through the juice-cup; Fig. 4, a detail in perspective of the j nice-cup; Fig. 5, a similar View of one of the strainer-plates.

Like numerals of reference indicate like parts in all the figures of the drawings.

The basel of the machine may be of any suitable construction, and is provided at its rear end with a vertical standard 2, having an opening 3 near its upper end, in which upon a rod 4 is pivotally mounted the rear end of a lever 5, extending longitudinally over the base and through a slot 6, formed ina vertical standard 7, at the front end of the base and terminating beyond said standard in an ordinary handle or hand grip 8. An opening 9 is formed in the hand-grip, through which is inserted a ring 10, (see dotted lines,) which may be loosely connected with an operating-rod 11, the lowerend of the rod being pivoted to an ordinary foot-lever 12, by which said handle and lever may be depressed by foot-power to perform the operations hereinafter described. A rod 13 projects from the base, and at its upper end extends through an opening 14 formed in the lever and between the lower edge of the lever and the base, and encircling the rod is a coiled spring 15, said spring serving to normally maintain the lever in elevated or raised position.

In rear of the standard 7 and directly under the lever 5 there is formed in the base a pair of diverging openings 16, eachof which 17, projecting below the base, an opening 16 being located at each side of the vertical path traveled by the lever 5. That portion of the base occurring between the openings 16 is provided with a vertical slot 18, in which is seated the butt of a vertical stationary blade or knife 19, the upper or cutting edge of which is preferably curved or V-shapedms shown.

Encircling the opening 16 is a cylinder or ring 20, provided at diametrically-opposite sides with internal recesses 21for the reception of the ends of the knife, and above said ring or cylinder projects the cutting-edge of the knife. The upper edge of the ring is internally flared, and slightly below its edge is provided with an annular recess or shoulder 22, subdivided, as is also the ring, by the vertical knife.

23 represents a pair of semicircular perforated straining plates of a size adapted to fit at each side ofthe knife or blade and within the recesses formed in the ring. The plates are perforated, and their upper surfaces are concaved and form a continuation of the flared upper edge of the ring, so that the two combined are adapted to receive the half of a lemon. The lever 5 is provided with a recess 24, into which the cutting-edge of the blade is adapted to take when the lever is depressed, and at each side of the recess the lever is provided with a convexed squeezer 25, each adapted to take into and substantially conform to the perforated straining-plates, which latter, it will be understood, may be readily removed for the purpose of cleaning.

is provided with a discharge orifice or nipple The diametrically opposite upper lateral edges of the rims are cut away and provided with a pair of bearings 26, registering with which are a pairof perforated bearing-standards 27, secured to the base, and in the bearings 26 and 27, at each side of the lever 5, there is mounted a rock-shaft 28, the rear end of which extends through the bearings 27, and a pair of rock-arms 29, connected to each other by a coiled spring 30. Small rockarms 31 also project from each shaft and are by the spring normally maintained in a flat position upon their respective strainer-plates. Each of the shafts is also provided with a cam-hook 34C, inwardly disposed, and is adapted to be engaged by a slot 35, formed in the lowerend of each of a pair of spring arms or plates 86, yieldingly supported and depending from the opposite sides of the lever 5.

A lemon to be cut is mounted across the fixed blade and the lever compressed. The lemon, it will be observed, will be divided into halves, and after thus being divided the squeezers will begin to compress the same, and the juice extracted, minus the seeds, pulp, 850., will pass through the perforations in the plates and out through their respective discharge-orifices. The .lever 5 may be operated by hand or by foot, and two glasses placed under the orifices will receive equal amounts of juice, or, if desired, a single receptacle may be placed thereunder to receive the entire amount of juice of one or a succession of lemons cut and squeezed. After the squeezing operation has been completed and the juice thoroughly extracted, the lever is released and thrown by a spring back to its raised position. As the lever is depressed the slotted yielding plates take under the cam-hooks of the rock-shaft, and when released said rock-shafts are, through their hooks and the plates, rocked or oscillated, so that the rock-arms lying in the lemon-extracting ring serve to discharge the rinds at each side of the machine.

Ilaving described my invention, what I claim is- 1. In a lemon-squeezer, the combination, With the base having opposite diverging discharge-openings, of a fixed knife mounted between and projecting above the same, a ring or cup encircling the opening, provided with perforations and receiving and subdivided by the knife, a pivoted lever mounted above the knife and provided with opposite squeezers, and with a slot for the reception of the blade of the knife, substantially as specified.

2. The combination, with a base having a pair of divergent openings, a ring mounted on the base encircling the openings and provided with an internally-flared upper edge and with an annular shoulder, a knife subdividing the ring and mounted in the base, and opposite strainer plates perforated and mounted in the recesses or shoulders, of a lever provid ed with opposite squeezers,havi ng an intermediate recess to receive the upper edge of the knife, substantially as specified.

3. In a lemon-squeezer, the combination, with the base having the opposite openings terminating in discharge-orifices, the surrounding flared ring mounted on the base and provided with an annular shoulder and diametrically-opposite vertical grooves, a knife seated in the base and in the grooves and subdividing the ring, and having its upper edge inwardly recessed, and opposite perforated concaved semicircular removable strai ner-plates mounted in the shoulders at each side of the knife-blade, of a pivoted lever mounted over the blade and provided with a recess for the reception of the same, and with opposite squeezers depending from the lever and adapted to take into the ring at each side of the blade, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

WILLIAM O. DUNLAP.
